Abstract
L'invention concerne un détecteur de gaz utilisant une géométrie de jonction à effet tunnel. Ce détecteur de gaz comprend une première couche de matériau électriquement conducteur, une couche de matériau électriquement non conducteur disposée sur la première couche de matériau électriquement conducteur, une deuxième couche de matériau électriquement conducteur disposée sur la couche de matériau électriquement non conducteur, une source de gaz (34) en communication fluidique avec la deuxième couche de matériau électriquement conducteur ; et une source d'alimentation en communication électrique avec le première et la deuxième couche de matériau électriquement conducteur. L'invention porte aussi sur un procédé de détection d'un gaz utilisant le détecteur susmentionné, ainsi que sur un procédé de fabrication d'un détecteur de gaz.
